## Abstract Surfaceβenhanced Raman spectroscopy (SERS) was applied to the study of silver electrodes in the presence of 2βmercaptopyrimidine (2MP) over a wide electrode potential range from β0.3 to β1.8 V (__vs.__ SCE). The spectra reveal that in neutral solution 2MP was adsorbed perpendicularly on

Surface-enhanced Raman spectroscopy has been used to study the surface chemistry of thiocarbohydrazide (TCH) on Ag and Cu electrodes. The TCH molecule is adsorbed on Ag and Cu surfaces through its S atom. The electrochemistry of TCH in acidic solutions is also investigated. In contrast to thiosemica
